And another thirty minutes or go elapsed without the relative positions of the two flying machines undergoing any perceptible change. In the course of this period the Parrott rose to an altitude, indicated by the barograph at Lanyard's elbow, of more than half a mile. Below, the Channel fog spread itself out like a sea of milk, slowly churning.
The speed of the WHIZZER was now about forty miles an hour, not fast for an air craft, but sufficiently speedy in trying out a new machine. Tom looked at the barograph, and noted that they had attained an altitude of seven thousand five hundred feet.
He shifted the elevating rudder, and the WHIZZER began to go up, slowly, for there was great lateral pressure on her large surface. But Tom knew his business, and urged the craft steadily. The powerful electric engines, which were the invention of Mr. Fenwick, stood them in good stead, and the barograph soon showed that they were steadily mounting. "Is the wind pressure any less?" inquired Mr.
By sliding the weights back we go up." He demonstrated this at once, sending his craft sliding up another hill of air, until it reached an elevation of four hundred feet, as evidenced by the barograph. "I guess this is high enough," remarked Tom after a bit. "Now to see if she'll stand still."
As he yelled there came a grinding, pounding noise, and the big ship seemed to waver, to quiver in the void, and to settle toward the earth. "Something's happened!" cried Ned, as he sprang for the place where most of the mechanism was housed. "Bless my toy balloon!" shouted Mr. Damon. "We're falling, Tom!" It needed but a glance at the needle of the barograph, to show this.
"We had no sooner taken wing than the aeroplane was sighted by German observers in captive balloons anchored about six miles distant. Immediately two Albatross machines rose from the German camp and came forward. "We continued to advance, meanwhile sending the aeroplane higher and higher until the barograph showed we were 6,000 feet above the ground.
At the same time Tom heard the hiss of the gas as it rushed into the envelope from the generating machine, as Ned opened the release valve. "Now we ought to go up," the young inventor murmured, as he anxiously watched the barograph, and noted the position of the swinging pendulum which told of the roll and dip of the air craft.
She'd jumped up half an inch in about two seconds, wiggled round some, and then come back to normal. You can see the curve yourself if you ask Fraser to show you the self-registering barograph. Some doin's, I tell you!" He nodded his head with an air of importance.
What is more interesting at sea than the charts of ocean depths, currents, winds, salinity, and temperature! If you go too fast to touch on Plankton, Nekton, and Benthos, at least let the poor first class passengers have a compass, if not a barograph and a thermometer, to eke out conversations on the weather, the day's run, and bridge.
A meteorological screen, containing thermometers and a barograph, had been erected on a post frozen into the ice, and observations were taken every four hours. When we first left the ship the weather was cold and miserable, and altogether as unpropitious as it could possibly have been for our attempted march. Our first few days at Ocean Camp were passed under much the same conditions.
